5 GENERAL BANNER AD GUIDELINES Audio:Must be user initiated with a clearly present on/off button. To allow for audio initiation in videos without player controls, a control may be included for user to initiate audio. Creatives may not expand past ad unit boundaries unless they are rich media ads built according to the specifications described under the Expandable Ads below. All audio and animation (including video) must stop upon exit click. HTML5 files: All HTML5 files must be gzipped. According to the IAB, this means that all assets for HTML5 ads must be packaged together for delivery. To optimize the file size for delivery to browser, all assets should be delivered in compressed format. The common method for compressing files in transition over the Internet is the gzip utility, which is free to use and supported by all modern browsers. Ad servers compress ad files they serve as part of their general process. Hotspot: Not to exceed ¼ size of ad. Initiated when cursor rests on hotspot for at least 1 second. Must NOT initiate audio. Defining ad space: Ad unit content must be clearly distinguishable from normal webpage content (ad unit must have clearly defined borders and not to be confused with normal page content). On all ads with partially black, white or transparent backgrounds, you must add a visible border of a contrasting color to the majority background color of the creative. Submission lead time: Minimum lead time for ad file submission is 3 business days for standard creative and five business days for rich media. All 3rd party ad tags are required to serve from secure servers (https). In addition, any image, pixel or video that is called during the serving of the creative must originate from a secure server. All creative must be free of applications including, but not limited to: Active X, viruses, exit pops, spyware and malware. Creative coding may not use cross-domain scripting or set cookies in unapproved domains. All creative must open in new windows. The target window for the click-through URL must be set to _blank so the click-through will open a new window. Do not leave the target statement undeclared. Rich media must be served by a 3rd party vendor. You must supply a default image. Content Restrictions: Tobacco, weapons, nudity, defamatory/hate content, illegal activities, profanities, or spyware. Offers of free gifts, links to quizzes and surveys, misleading claims, and references to sex or sexuality. Max CPU: Ad not to exceed 30% CPU usage during hostinitiated execution. Interest-Based Advertising (IBA): Include IBA selfregulation controls for ads using behavioral targeting (5KB max file size). Max number of host-initiated file requests: Ad not to exceed 15 file requests during initial file load and host-initiated subload. Unlimited file requests allowed after userinteraction.

6 IN-BANNER VIDEO GUIDELINES Video Formats: Click to play: Creative initially displays as a static image, then the video plays once a user clicks on the creative. Autoplay with no sound: Video automatically plays without sound until a user clicks on the creative. Hover to play: Video plays after a user hovers over the creative. Creative Requirements: Flash creatives for in-banner video ads can be hosted directly by Sojern provided they comply with generic display requirements. HTML5 creatives can be hosted by Sojern as long as they are gzipped to the acceptable file size. General Requirements: Creative must include a user-initiable replay button. Total playing time must be 4 minutes or less. Click to Play: Image GIF/JPG : 40KB initial load, 2.2 MB total load with video. Video Dimensions: 300x250 (inline rectangle) and 336x280 (large rectangle). Aspect ratio 4:3 is recommended; other aspects will be accepted but may be letter boxed. Border 1x1 contrasting border is suggested. Frame Rate: Minimum 14 frames-per-second (30 FPS recommended). Audio: Must be encoded at a volume less than or equal to -12dB. Animation: 30 seconds maximum. Opening image can t be animated. Audio and video must play only upon user s click. Start and stop or mute buttons are required. Hover to play For hover-over initiated ads, we require 2 seconds of hovering before audio is initiated. When the user is no longer hovering, the audio must stop. The video (animation) can start at any time (without initiation) as long as the animation is less than 30 seconds and the audio requirements are met.

7 EXPANDABLE AD GUIDELINES Expansion method must be user initiated Expand: On-click or on-hover Close: On click or mouseoff Maximum file size: 50K (recommended) up to 150K for the initial load up to 2.2M for the polite load. Maximum size per panel: 200K. Required controls: Panels must contain a prominent Close X, in 16 point font or larger, on the corner of the unit. Audio: User-initiated on click only. Depending on its placement, an ad must expand in one plane (either left or right, up or down) only. The ad may not expand in two directions at the same time. Expandable ads currently depend on use of JavaScript. Iframe tags cannot be used. Approved expandable ads rich media vendors include: DoubleClick Rich Media, eyereturn Rich Media, EyeWonder Rich Media, Flashtalking Rich Media, Interpolls Rich Media, Linkstorm Rich Media, MediaMind Rich Media, Mediaplex Rich Media, Oggifinogi Rich Media, Pointroll Rich Media If rotating videos in a banner ad, support is available for up to 5 videos in 20% rotation.

9 EXPANDABLE VIDEO AD GUIDELINES Audio is not allowed for companion ads. Creative needs to have a specified click-through URL. When clicked on, it must open in a new window. The majority of VPAID (interactive videos) are Flash. If they run in Chrome, the video will be paused automatically. VAST 2.0 tags should be largely unaffected as the majority are HTML5-compliant. All 3rd party ad tags are required to serve from secure servers (https). In addition, any image, pixel or video that is called during the serving of the creative must originate from a secure server. (It is not mandatory to serve video ads from a third party.) Creative can be updated with the skippable flag. Generally, any ad beyond ones that qualify for a 15 second slot must be skippable. Support all ad video servers that are VAST 2.0 compliant. No restriction on the file size of the backup GIF/JPG but is dependent on the individual exchange requirements. Note, all video creative uploaded will be transcoded into the following formats (downscaling only, no upscaling): FLV: 426x240, 640x360, 854x480 3GPP: 176x144, 320x240 MP4: 640x360, 1280x720 WEBM: 640x360, 854x480, 1280x720, 1920x1080

11 Facebook Ads: News Feed FILE FORMAT GIF, JPG, or PNG FILE SIZE FBX image creative can be up to 500K DIMENSIONS Suggest images that are 1200x628 (1.91:1 aspect ratio), but any image at least 600 pixels wide is supported. Older creative images that satisfy an earlier version of these requirements are still supported for pre-existing creative, but all new creative must use the new creative dimension requirements. CONTENT Title: Up to 55 characters Message: Up to 215 characters Body: Up to 200 characters Caption URL: Up to 30 characters Click-through URL: Up to 1024 characters Image Text: images can t be more than 20% of the text 3RD PARTY TRACKING For impression tracking, please provide a secure (https) 1x1 pixel Tag must not drop more than one cookie Tag does not redirect more than once VIRAL PROPENSITY Social elements appear directly below the ad unit and are visible with each insertion. Notifications of comments, viral engagement, insights and communication can be moderated on your unpublished News Feed Ad on your Facebook page (with proper admin rights). When users like a comment on a News Feed ad, it will trigger viral impressions of that ad in their friends News Feed. These viral impressions will never fire view tags, but will result in more outbound clicks that fall on the landing page from that ad. This benefit of free outbound clicks is the only value that social distribution provides to FBX.

Choose clear images with colors that look vivid against Facebook s blue and white. Create text with a clear Call to Action. Run promotions and test free offers, discounts or loyalty programs to drive sales. Capitalize words that draw attention like FREE or SALE. Create multiple variations of the ads for A/B testing. There are user-level caps that prevent users from seeing too many ads consecutively, overall, and from a specific page on a given day. For that reason, we highly recommend running News Feed in conjunction with Right-Hand Column ads.
